Classification On Poeobius Heath, 1930 Fisher wrote (1946, p.218) "A tenable hypothesis is that the echiuroids and Poeobius stemmed from a common group that was as fundamentally unsegmented as the Amphineura among mollusks. According to this view Poeobius is the survivor of a lesser phylum, comparable to the Phoronidea and Priapuloidea. As the genus now floats in a sort of taxonomic limbo, it may be provisionally assigned to a new phylum, POEOBIOIDEA." However, the annelid nature of Poeobius was discovered soon after (Pickford, 1947). Hyman (1959: 697, 'Smaller Coelomate groups') dismissed the idea of a new phylum with the words "Poeobioidea is therefore to be obliterated." [details]
Etymology Heath gives an etymology from Greek, with 'Poeus' he says meaning 'of what nature' and 'Bios' meaning 'life', so presumably he was indicating the uncertain affinities of the worm, and 'meseres' he says means intermediate. So he apparently was using the epithet to answer the question he posed with the genus name - of what nature of life [was this], and the answer was an intermediate [form of life]. [details]
